I ran out of gas running residentials (close to Emory University in Atlanta) in an old "piece of doodoo" p-800. This car had a broken gas gauge. So I took a chance and left the building without gassing up (bonehead decision). When I ran out of gas a man in his house just happen to hear my engine go out. He came out of his house with a gas can. After he emptied his gas can into my package car, I broke off my route to get gas and then finished my route. So needless to say that prevented a call to the Center manager to inform him/her that I ran out of gas running my route.
